A large number of flood-related fatalities in urban areas are due to drowning of people in vehicles. Therefore, reliable models of the vulnerability of vehicles impacted by flow are necessary for risk assessment and emergency management. This paper includes the effect of the sloping terrain in a four-parameter dimensionless conceptual model of the stability of vehicles impacted by flow. A set of parameters was calibrated on the basis of experimental data from the literature in order to reproduce the average stability limits of a wide range of vehicles tested in laboratory conditions. These parameters can also be used to represent the average stability conditions of a wide variety of circulating vehicles as required in flood risk mapping.

洪水中车辆稳定性的概念模型

城市地区与洪水有关的大量死亡是由于人们在车辆中溺水造成的。因此，受流量影响的车辆脆弱性的可靠模型对于风险评估和应急管理是必要的。本文将倾斜地形对流动影响车辆稳定性的四参数无量纲概念模型的影响包括在内。根据文献中的实验数据校准了一组参数，以重现在实验室条件下测试的各种车辆的平均稳定性极限。这些参数还可用于表示洪水风险绘图中所需的各种循环车辆的平均稳定性条件。
